Abstract:Migration of gases from geo-energy wells has the potential to impact groundwater and surface water and to emit greenhouse gases into the atmosphere. Gas migration is complex, which complicates detection and monitoring in the field. Multicomponent mass transfer is known to impact the dissolution of trapped gas; however, these effects have not yet been quantified in the context of gas migration. In this study, gases of varying compositions were trapped in a sand-packed column, and dissolved gas concentrations we… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
